SAP S/4HANA Error 680: SQL Statement Hint Issue
Description
Error 680, ERR_SQL_STATEMENT_HINT, indicates a problem with a SQL statement hint used within an ABAP program or custom report in SAP S/4HANA. This typically occurs when the database optimizer cannot interpret or apply the specified hint, preventing the query from executing as intended.
Error Message
ERR_SQL_STATEMENT_HINT
Known Causes
3 known causesInvalid Hint Syntax
The SQL statement hint contains syntax errors, misspellings, or incorrect parameters that the database optimizer cannot parse.
Unsupported Hint
The specified hint is not recognized or supported by the underlying database system (e.g., SAP HANA) or its current version.
Object Reference Error
The hint refers to a database object (like a table or index) that does not exist or is inaccessible in the current database schema.
Solutions
3 solutions available1. Remove Invalid SQL Statement Hints medium
Identify and remove incorrect or obsolete SQL statement hints from ABAP code.
1
Identify the problematic ABAP program or query. The error message or surrounding logs should provide clues to the specific statement.
2
Use transaction SE80 (Object Navigator) or SE38 (ABAP Editor) to locate the ABAP program.
3
Search within the ABAP code for SQL statements that might be using hints. Common syntax for hints might involve `UP TO n ROWS`, `ORDER BY`, or specific database hints like `USE_NL`, `USE_HASH`, etc.
4
Review the SAP Notes related to the specific version of S/4HANA and the database being used (e.g., SAP HANA). Some hints might be deprecated or have changed syntax.
5
Comment out or remove the identified invalid hint. For example, if you find `SELECT * FROM ... UP TO 10 ROWS`, and this is causing issues, try removing `UP TO 10 ROWS` if it's not strictly necessary or if it's being used incorrectly.
DELETE FROM my_table WHERE ...;
-- SELECT * FROM my_table WHERE ... UP TO 10 ROWS. -- Removed hint6
Save and activate the modified ABAP program.
7
Test the application to ensure the error is resolved and the functionality remains correct.
2. Update ABAP Kernel and Database Client Libraries advanced
Ensure the ABAP kernel and database client libraries are compatible and up-to-date.
1
Check the SAP Support Portal for the latest recommended SAP Kernel patches for your S/4HANA version.
2
Review SAP Notes that specify compatibility requirements between the ABAP kernel, the database version (e.g., SAP HANA), and the corresponding database client libraries.
3
Plan and schedule a downtime window for the S/4HANA system.
4
Apply the latest SAP Kernel patches using transaction `SPAM` (Support Package Manager) or `SAINT` (SAP Add-On Installation Tool).
5
If necessary, update the SAP HANA database client libraries on the application servers. This process can vary depending on the operating system and HANA client version. Consult SAP Notes for specific instructions.
6
Perform thorough testing of critical business processes after the updates.
3. Analyze and Optimize SQL Statements with Database Tools advanced
Use SAP HANA Studio or Cockpit to analyze the execution plan of problematic SQL statements and identify hint-related issues.
1
Identify the specific SQL statement causing the error. This might require debugging the ABAP code or reviewing system logs.
2
Connect to your SAP HANA database using SAP HANA Studio or SAP HANA Cockpit.
3
Navigate to the SQL Console or a similar tool that allows you to execute SQL statements.
4
Execute the problematic SQL statement and analyze its execution plan. Look for indications of inefficient hint usage or hints that are not being applied as expected.
EXPLAIN PLAN FOR <your_sql_statement>;5
If the execution plan reveals issues related to hints (e.g., the optimizer is ignoring a hint, or a hint is forcing an inefficient plan), consider removing or adjusting the hints in the ABAP code. Alternatively, explore database-specific optimization techniques.
6
If the issue is related to the database's ability to interpret specific hints, consult SAP Notes for the correct syntax and supported hints for your SAP HANA version.
7
Re-test the ABAP application after making any necessary adjustments to the SQL statements or hints.
